Abstract: A brewing device for a beverage preparation machine, in particular coffee or tea, the brewing device includes a frame, a brewing chamber carried by the frame and having a longitudinal axis and a loading/unloading aperture for a brewable material, a closing body movable relative to the frame from and to a closing position for the aperture, and an actuator device to move the closing body. The brewing device further includes a motor and a transmission arranged between the motor and the closing body; the transmission includes a rack-and-pinion mechanism including a driving toothing carried by the frame, and a driven toothing carried by the closing body and meshing with the driving toothing to move the closing body from and to its closing position.

Abstract: A brewing device for a machine for preparing beverages like coffee or tea has a brewing chamber with a longitudinal axis, a frame having two walls arranged on opposite sides of the brewing chamber, and a fastening device. The fastening device is configured to releasably couple the brewing device to a support body in the beverage preparation machine and includes a lever release device hinged to the frame to rotate about an axis transverse to the longitudinal axis between a normal coupling position, in which the lever release device stably holds the brewing device on the support body, and a release position, in which the lever release device allows the brewing device to be released from, or mounted on, the support body.

Abstract: The present disclosure is for an electronic control system for a brewing device for a machine for preparing beverages, in particular coffee or tea. The brewing device comprises a brewing chamber having an opening through which a material to be brewed may be loaded and discharged; a closing body movable away from and towards a sealed closing position of the opening angularly spaced apart from the closing position, through an intermediate ejection position, in which the closing body is raised with respect to the closing position along the longitudinal axis of the brewing chamber; a piston slidably mounted in the brewing chamber in a position axially opposite the closing body; a first electric actuating device for the movement of the closing body; and a second electric actuating device for the movement of the piston.

Abstract: A brewing device is used for preparing beverages like in particular coffee or tea. The brewing device includes a brewing chamber with an opening for loading/unloading a brewing material, a piston slidably mounted in the brewing chamber and an electronic control unit. The electronic control unit is programmed to cause the piston to move among a loading configuration, in which the brewing material is loadable in the brewing chamber, a compression configuration, in which the piston compacts the brewing material in the brewing chamber, and an expulsion configuration, in which the piston extracts the exhausted material from the brewing chamber. The electronic control unit is programmed to cause, in the loading configuration, the piston to lower from a higher position, corresponding to an initial loading configuration, to a lower position, corresponding to a final loading configuration.

Abstract: A collection container to collect exhausted powder material discharged by a brewing device in a beverage preparation machine. The collection container has a receiving zone to receive the exhausted powder material and is provided with conveying means operable to convey the exhausted powder material so as to spread it inside the collection container and reduce its piling up in the receiving zone.
